Cryptanalysis is the study of methods for obtaining the meaning of encrypted information without access to the secret information that is typically required to do so.

Cryptanalysis refers to the study of ciphers ciphertext or cryptosystems with a view to finding weaknesses in them that will permit retrieval of the plaintext from the ciphertext without necessarily knowing the key or the algorithm.
